Bra Size Calculator — free online
Bra shopping gets confusing fast. The number on the label means one thing in the US, something else in the UK, and a third thing in Europe. If you've ever bought the wrong size online or stood in a fitting room guessing, you know the feeling. We added a free tool that sorts it out — Bra Size Calculator — right in your browser.
What it does
You type in two measurements: around your ribcage just under the bust (your underbust) and around the fullest part of your bust. From those, it works out your band size and cup size, and shows the matching sizes in US, UK, EU, French and Belgian, Australian, and Italian systems side by side. So you can shop from any shop, anywhere, and know what to pick.
Nothing leaves your device
The whole thing runs in your browser. Your measurements aren't sent anywhere, nothing is uploaded, and nothing is saved. When you close the tab, it's gone.
How to use it
- Open Bra Size Calculator.
- Enter your underbust and bust measurements.
- Read your band size, cup size, and the matching size in every country's system.
It's free with no limit. There are more small tools on the Apps page.
